Social Network Measures using Matrices // Provides measures to describe and manipulate one-mode, two-mode, multiplex, and multilevel networks using matrix algebra. Implements functions for network centrality, cohesive subgroups, structural holes, similarity measures, path distances, signed networks, and random network generation. Supports ego-centric and whole- network analyses, including dyadic and triadic census, structural balance, and bipartite projections.
